whereby the end convolution of a bed spring may be easily and quickly locked to the cross rails of a bed spring 1n a manner whereby the convolution of the helical bed spring will be securely held against lateral displacement, The locking arrangement obviates the use of special tools, or tools of any kind for twisting wire thereby allowing bed springs to lie-easily and quickly assembled by unskilled labor.

A further object is to provide helical bed springmounting comprising tie wires e"-;tending transversely through apertures of the cross rails of the bed spring and having oliset portions disposed in saidapertures; and adja ent apertures in the cross rails, through which thelower convolutions of the helical bed spring; extends, said conv'olutions beine inferenga ed with the tie wires in a manner wherel a downwardpressure is applied on the tie wires adjacent the ends of the offset portitms oi said tie wires thereby insuring a binding loelriuop eng gement o the tie wires and the cou'miution oi the helical spring. the helica spring convolution er-rtends pre vents ion it-udinal displacement oi? the helical sprin ation to the cross raih and the oilset portion of the tie wires prevents transversedisplacementof the helical spring in relation to the crossraih thereby rigidly holding ment. v

With the above and other objectsin view the invention resides in the combination and arrangement of parts as hereinafter set forth shown in the drawing; described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing Figure 1 is a perspective view of a portion of cross rails of a bed spring, showing the helical spring locking means applied thereto.

the helical spring against displace 'lhe apertures through which Vll igure 2 is a side view of a conventional lorni oi double helical bed spring.

Figure 3 is a side elevation of a lic l bed spring. i

it er-ring to the drawing, the numeral 1. designates spaced cross rails of. a bed spring frame, which rails are formed from metal Extending transversely through the rails l and through apertures 2, therein, are tie wires 3, which. wines are provided with segmentally shaped offset portions d, which are received in the apertures 2. The offset por: tions 4 are placed inthe tie wires 3; in

S111 gie any suitable manner, for instance by crimping and are in the wires 3 when they are placed through the rails 1.

The offset portions 4:" are in opposed positions to each other, as shown in Figure 1 thereby forming shoulders 5 on opposite sides of the rails 1, and located. inwardly in relation to the apertures 2. i The helical spring 6, the lower portion of which is shown in Figure 1 for purpose of clearness, is locked to the cross rails 1 and to the tie wires 8 by passing the end 7 of its lower c0nvolution 8 under one oi? the tie wires3,, and in engagement with one of the shoulders thence through the aperture 9 in the cross rail 1, andthence under the offset portions of the adjacent tie wire 8, after which the end 7 is passed over the tie wire 3 i n engage ment with the shoulder 5. The operator during; this operation ri'lides the end 7 ol, the convolution 8 while imparting a rotary movement-to the coiled spring. 'As the helical s iring rotated the op rator guides the end '2 under the opposite tie wire 3 into gageinent with'the shoulder 5 of the other offset portion 4, and thence through the aperture 9% after which. the end 7, is guided underthe adjacent offset portion 4 and over the tie wire 3 into engagement with the adjacent shoulder 5. "It will beseen that the entire operation is accomplished without the use of tools of any kind and that the looking operation may be quickly accomplished and consequently a bed spring may be assembled with minimum amount of time, and by unskilled labor. During the locking operation the convolution 8 is passed under and over the tie wires 3, at the shoulders 5, and consequently the spring action of the convolution 8 sligtly bends or flexes the tie wires 3, which bending, in combination with the constructive action oi the convolution 8 in sures a positive holding of the convolution and positively prevents lateral displacement of the secured ends of the helical springs 6. By providing the spaced apertures 2 and 9, it is obvious that when the convolution 8 of the helical spring 6 is in engagement with the shoulders 5 of the tie wires 3, the convolution 8 and offset portions 1, which extend through the apertures 2, 9, and 9*, will engage the walls of said apertures, in a manner whereby transverse lateral movement in relation to the cross rails will be prevented, and any movement in this direction will only tend to more tightly bind the convolutions 8 to the tie wires at the shoulder 5.

Referring to Figure 8 wherein a single helical spring is used, the small convolution 11 thereof is secured in position above the rail lin substantially the same manner as that shown in the double helical spring, however in this form the convolution 11 is only passed through the aperture 9, and has abearing on the upper side of the rail 1, which is sufiicient for the small end of a single helical spring, otherwise the operation is substantially the same.

Fromthe above it will be seen that a helical bed spring locking device is provided, which device is simple in construction, and constructed in a manner whereby helical bed springs may be locked simply by imparting a rotation to the helical bed springs and interengaging its end convolution with the cross rails through apertures and with the tie wires, and when interengaged, the helical bed spring will be positively held against lateral displacement. The upper ends of the helical springs may be tied together in any suitable manner.

The invention having been set forth what is claimed as new and useful is 1. The combination with a cross rail of a bed spring frame, said cross rail being provided with spaced pairs of apertures, and an end convolution of a helical bed spring extending through the inner apertures of the spaced pairs, of tie wires extending transversely of the rail through the outer apertures of the pairs and interwound with said convolution, by means of which the said convolution is locked to said rail and the tie wires.

2. A helical spring locking device, said device comprising a cross rail having spaced pairs of apertures, tie wires extending transversely of the rail through the outer apertures of the spaced pairs of apertures, the end convolution of the helical spring being interwound with the tie wires and extending through the inner apertures of the spaced pairs of apertures.

3. A helical spring mounting and locking device, said device comprising a cross rail having substantially horizontally alined spaced pairs of apertures, tie wires extending transversely through the outer apertures of the spaced pairs of apertures, the end convolution of the helical spring being interwound with the tie wires and extending through the inner apertures of the spaced pairs of apertures.

4. A helical spring mounting and locking device, said device comprising a cross rail having spaced pairs of apertures, tie wires extending transversely through ,the outer apertures of the spaced pairs of apertures, said tie wires being provided with oppositely extending offset portions disposed in the outer apertures of the spaced pairsof apertures, the end convolution of the helical spring being interwound with the tie wires in engagement with the ends of the offset portions of the tie wires and extending through the inner apertures of the spaced pairs of apertures.

5. The combination with a bed spring frame cross rail having spaced pairs of apertures, tie wires extending transversely through the outer apertures of the spaced pairs of apertures, of means for mounting a helical spring on said cross rail, said means comprising offset portions carried by the tie wires and disposed in the outer apertures of the spaced pairs of apertures, the end convolution of the helical spring extending over and under the tie wires, through the inner apertures of the spaced pairs of apertures and in engagement with the ends of the oifset portions of the tie wires.

6. The combination with a bed spring frame cross rail, tie wires extending transversely through said rail, a helical spring disposed above the rail, of means for locking the end convolution of the spring to the rail and tie wires, said means comprising the interwinding of the end convolution of the helical spring with the tie wires and through apertures in the rail adjacent the tie wires.

In testimony whereof I affix my signature.
